Plenty of experience looking at Wiki. Integrity too, reading the paragraph about Turner. More positives than negatives. We won't know if whoever is appointed will be be successful or not so everyone is a gamble.
"After he finally retired as a player, John Cartwright became an assistant coach at the Penrith club and the Sydney Roosters. In 2000 he was awarded the Australian Sports Medal for his contribution to Australia's international standing in rugby league. [citation needed]
Cartwright began coaching at Penrith as the reserve coach in 2001. After a period as assistant to Ricky Stuart at the Sydney Roosters, as well as coaching the United States national rugby league team against the Kangaroos in 2004,[5] Cartwright was appointed the inaugural coach of the Gold Coast Titans after their admission to the National Rugby League.
He became involved in a feud with Melbourne Storm winger Steve Turner over contractual obligations. "We flew him up, showed him around for two or three days and he agreed to me that he would come here, we shook hands. He looked me in the eye. The deal was done. He even started looking for accommodation. I only coached him in a couple of games at Penrith and my reaction has been the same as it would be for any player in this situation. But to do what he has done . . . I'm not happy. I'm extremely disappointed, to say the least." [6]
In 2009, he was selected to coach the NSW Country Origin side. He later guided to the Gold Coast to consecutive finals appearances in the 2009 NRL season and the 2010 NRL season, the latter of which saw the Gold Coast reach the preliminary final. In 2011, the Gold Coast claimed their first Wooden Spoon under Cartwright's coaching.[7]
After four years without making the finals, on 5 August 2014 he announced that he would stand down as head coach of the Gold Coast, with immediate effect. He would coach the club one last time against the Sydney Roosters in Round 22 before Neil Henry taking over on an interim basis.[8]
In February 2015, Cartwright joined the North Queensland Cowboys as an assistant to head coach Paul Green.
On 4 October 2015, John Cartwright was a member of North Queensland's coaching staff in the side's 17-16 Grand Final victory over the Brisbane Broncos.
In the weeks following the Grand Final win, Cartwright quit the North Queensland club and returned to Sydney as an assistant coach of the Manly-Warringah Sea Eagles.[9]
Following the 2020 NRL season, Cartwright was announced as an assistant coach for the Brisbane Broncos, working under their new head coach Kevin Walters."
